Peracetic Acid Analyzer – PeraSense
Online, continuous Peracetic Acid Analyzers, Peracetic Acid Monitors, Peracetic Acid Meters and Peracetic Acid Controllers make up the PeraSense range which utilizes the very latest and best peracetic acid sensors available in the world today. It is a membraned device which uses no reagents, is extremely stable, and has reduced maintenance and reduced whole life costs.
The PeraSense peracetic acid sensors, which give a peracetic acid measurement in ppm or mg/l, and a range of flow cells, are available with different peracetic acid controllers giving you the same great performance with different communication, display and control options. With the PeraSense range of peracetic acid analyzers, you get everything that you need – and nothing that you don’t.
The PeraSense Peracetic Acid Monitor is used in many applications requiring the measurement of peracetic acid concentration simply for peracetic acid monitoring or peracetic acid dosing control.
Cost of ownership
Pi’s peracetic acid analyzer is designed to have reduced maintenance, reduced calibration and reduced spares requirements. The PeraSense CH3CO3H analyzers are undeniably the most cost effective CH3CO3H analyzers available. In most situations the PeraSense analyzer is able to control the dosing of CH3CO3H by adjusting flow rates, pump rates, or valve positions automatically to maintain the peracetic acid set-point. Automatic dosing can significantly reduce reagent costs, and increase the level of control.
- Amperometric sensors – continuous online peracetic acid ppm measurement
- No chemical reagents – lower cost of ownership
- Stable and reliable – excellent process control
- Suitable for all potable and process waters including seawater

Pi’s PeraSense peracetic acid sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options.
The PeraSense peracetic acid analyzer can be installed in a variety of auxiliary flow cells and self-cleaning devices.
AutoFlush – The PeraSense sensors can come equipped to automatically clean themselves at user defined intervals, with all the benefits of no operator intervention for up to 6 months. The AutoFlush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample.
Multi-Sensor Systems – The whole range of PeraSense Peracetic Acid Monitors and Controllers can be fitted with additional sensors such as conductivity or pH. Please ask your local distributor for more details.
Communications –The CRONOS® and CRIUS®4.0 controllers can be equipped with data-logging, relay outputs, analogue outputs and serial communications such as: Ethernet, Modbus and Profibus. Remote monitoring of the instruments (including remote access to control all instrument settings) is available via the internet over GPRS and via a LAN. In fact the CRIUS®4.0 PeraSense monitor has all the options you could want, whilst the CRONOS® provides a low cost alternative and is particularly great value for money!
The membraned amperometric peracetic acid sensor is a two electrode sensor which operates at an elevated applied potential which in turn eliminates zero drift. Its unique design means that no reagents or buffers are required at all and calibration is a simple one point (no zero required) operation. In addition to the state of the art amperometric peracetic acid sensor, the PeraSense range of controllers has all the functionality that you need.
Choose from the CRONOS® or CRIUS®4.0 controller to give you the highest quality peracetic acid monitor, with all the functionality you need, at the lowest price possible. This means that you pay for everything you need, and nothing you don’t, without sacrificing the quality of measurement.

FAQs
What is Peracetic Acid?
What sensor ranges are available for peracetic acid?
- 0.5-200mg/l
- 5-500mg/l
- 5-1,000mg/l
- 5-2,000mg/l
- 50-5,000mg/l and
- 50-10,000mg/l
How often does my sensor need calibrating?
Pi’s peracetic acid sensors have very low drift rates so how often you calibrate your sensor, depends on the application. Our customers range from people who calibrate once a week to once a month, even to once every six months.
How often does the peracetic acid electrolyte need to be replaced?
This is dependent on the water quality, but usually every 3-6 months.
How often does a peracetic acid membrane need to be replaced?
This is dependent on the water quality, but usually once a year.
If the pH changes, will it affect my peracetic acid reading?
Yes, but only if you are using the sensor at above pH 7. If this is the case, please contact Pi to discuss your application.
Are there any interferences?
Yes, chlorine dioxide and ozone. Contact Pi for more information.
How long can the membranes and electrolyte be stored?
Two years in a cool, dry place.
What are the MoCs?
PVC-U, stainless steel and a hydrophilic membrane.
Why does the peracetic acid sensor have no zero adjustment?
Pi’s peracetic acid sensors work at a positive voltage all the time. This means that any drift is negligible when compared to the positive operating voltage and therefore, no zero is necessary.
If the temperature varies, what will happen?
Nothing. Sensors are often affected by temperature, but the PeraSense has a built-in internal thermistor that allows for automatic temperature compensation meaning that you don’t have to worry about variations in temperature.
What is the best way to calibrate my peracetic acid sensor?
We recommend using a handheld colorimetric DPD meter. An alternative is the electrochemical test kit, Kemio from Palintest. This is currently proving to be a very popular device.
I am going to take a sample to do a test. What do I need to be aware of?
There are three main factors to think about;
I am going to take a sample to do a test. What do I need to be aware of?
There are three main factors to think about;
- Take the sample from right at the instrument
- If the concentration is changing quickly, do not take a sample
- Use a reliable handheld meter and be sure to follow the instructions
During the calibration process, the analyzer has warned me that the sample isn't stable. Why?
During calibration, the CRONOS® or CRIUS®4.0 controller monitors the stability of the probe signal. If this stability varies by more than 10% during the countdown, then the CRONOS® or CRIUS®4.0 will prevent calibration to prevent errors.
